Advanced cataract with hard lens nuclei frequently challenge the ophthalmologic surgeon when doing phacoemulsification. In the present study, we examined the effect of a new phaco tip design during cataract surgery.
100 patients were assigned to two groups. In group 1 (50 patients), the Kelman tip design (Alcon) was used during phacoemulsification, while in group 2 (50 patients), the Intrepid Balanced Tip was applied. Trypan blue was used in both groups, if necessary, to stain the anterior lens capsule prior to capsulorhexis.
Preoperative visual acuity was 0.11 ± 0,16 (decimal equivalent; means ± standard deviation) in the Kelman tip group and 0.10 ± 0.14 in the Intrepid Balanced Tip group (p > 0,05). Applied cumulative displaced energy was 43.38 ± 21.84 s% in the Kelman tip group and 21.55 ± 13.25 s% in the Intrepid Balanced Tip group (p < 0,001). No intraoperative or postoperative complications occurred.
The improved Intrepid Balanced phaco tip design has led to a significant reduction in ultrasound energy required to successfully perform phacoemulsification in medium to hard lenses.
在进行白内障超声乳化手术时，伴有硬核的晚期白内障常常给眼科医生带来挑战。在本研究中，我们检查了一种新型超声乳化针头设计在白内障手术中的效果。
100例患者被分为两组。在第1组（50例患者）中，超声乳化手术期间使用Kelman针头设计（爱尔康公司），而在第2组（50例患者）中，应用Intrepid平衡针头。两组在必要时均使用台盼蓝在撕囊前对晶状体前囊进行染色。
Kelman针头组术前视力为0.11±0.16（小数等效值；均值±标准差），Intrepid平衡针头组为0.10±0.14（p>0.05）。Kelman针头组应用的累积移位能量为43.38±21.84 s%，Intrepid平衡针头组为21.55±13.25 s%（p<0.001）。未发生术中或术后并发症。
改进后的Intrepid平衡超声乳化针头设计显著降低了在中到硬核晶状体中成功进行超声乳化所需的超声能量。
